BREAST FOR CARDING-IVIAGI-IINES.

Application filed February 8, 1915.

To all whom it may concern:

Be it known that I, Enno V. BATES, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Breasts for carding-Machines, of which the following is a specification.

This invention relates to carding machines especially to those used in the handling of wool fibers.

It is substantially an attachment for carding machines which takes the stock before it is well started on the main cylinder and breaks up the lumps, mixes and straightens the stock and saves wear and tear on the card clothing in various ways and especially by preventing lumps on the main cylinder which lumps have a tendency to wear out the card clothing in spots. If such lumps get on to the main cylinder, they are forced well into the teeth thereof and although the workers pick off small quantities, the lumps are not entirely destroyed but are finally removed with the Web by the fancy and dofi'er and make uneven work. My device breaks up and destroys these lumps before they reach the main cylinder and delivers to it a thin, even, unbroken web. My device also thoroughly mixes the stock and helps to straighten the fibers before they reach the main cylinder. It permits the speed to be increased thus increasing the production and helps to produce a better and stronger yarn with less Waste. This attachment may be placed upon any card either the first breaker, second breaker, intermediate or finisher.

lVhile it is useful upon the first breaker, it does better Work on the second breaker and finisher.

My device can be placed upon a card of any usual construction with Very slight changes therein and without occupying any additional floor space.

In the drawings, Figure 1 is a side elevation of a carding machine with my attachment. Fig. 2 shows a modification.

H is the main cylinder, 10 and 20 are workers, 21 and 21 are stripper Workers and 11, 11 are strippers of well known construction.

12 is the fancy and 13, 13 are dofi'ers of well known construction. The type shown are ring dofiers.

The feeding-in rolls K and L are of the Specification of Letters Patent.

usual construction having teeth which pitch in the usual way and which revolve in the usual way.

The licker-in E is of the well known c011- struction and has teeth which pitch in the same direction with those of the main cylinder and it revolvesin the same direction with the main cylinder. It therefore carries the stock from the feeding-in rolls upward over its top instead of underneath.

It may be of advantage in the first breaker to have a licker-in which carries the stock downward, as this permits seeds, sticks, etc. to drop upon the ground, but in the second breaker and finisher, the seeds and sticks have largely been disposed of. The stock is smoother and more even. Besides this, the carder can readily see if there are too many lumps as the licker-in runs slowly enough for them to be observed.

The tumbler F is of the usual construc tion. It has teeth which pitch in the opposite direction to those on the licker-in and on the main cylinder and it revolves in the opposite direction thereto. Its teeth are in stripping contact with those on the licker-in so that it will clear them and keep them clear. Its teeth on the other side are also in stripping contact with the main cylinder and at the top, with the breast.

40 is the main frame of the card and 41 is the rearwardly extending bracket of a well known construction which supports the licker-in, the feeding-in rolls, the tumbler and my attachment.

What I will call the first worker C is of an usual construction and is what I will call a forward running worker. Its teeth pitch in the same direction with those on the main cylinder but it revolves in the oppoite direction. Its teeth are in carding contact with the main cylinder H.

The breast cylinder D has teeth which pitch in the same direction with those of the first worker C but it revolves in the opposite direction. Its teeth are in carding contact with those on first worker C and in stripping contact with the teeth of the tumbler F. This breast is preferably smaller than the main cylinder. and preferably rotates in the same direction with the main cylinder and its teeth pitch in the same direction with those on the main cylinder.

Between the licker-in E and breast cylinder D, I locate a carrier roll A. which has the opposite direction touch to those on the licker-in' and breast and which revolves in the opposite direction. Its purpose is to transfer the whole or substantially all of the stock from the licker-in to the breast. I'also use a transfer roll 13 with teethwhich pitch in the same direction with those on carrier roll A. and which revolves in the same direction, in stripping contact with firstworker C and breast D.

Q In regard to speed, the licker-in E travels at a relatively low surface speed as for instance, 200 feet per minute. The carrier roll A travels at a faster surface speed as for instance, 400 feet per minute. The breast 1) travels at a faster Surface speed as for instance, 600 feet per minute. The tum- I bler F travels at a still faster surface speed as for instance, 800 feet per minute. The main cylinder travels at a still faster surface speed as for instance, 1200 feet per minute. The first worker C travels at a slow surface speed as for instance, 30 feet per minute and the transfer roll B travels at a faster surface speed than the first worker C but at a slower surface speed than the breast cylinder 1) as for instance, 300 feet per minute.

Considering the tops thereof, main cylinder H, breast D and licker-in E travels from' left to right, while first worker C, transfer roll B, carrier rollA, and tumbler F travel from right to left. Considering the tops thereof, the teeth of main cylinder H, first worker C, breast D and licker-in E pitch to the right while those on transfer roll B, carrier roll A and tumbler F pitch to the left. Adjoining cylinders and rolls are all so set that their teeth are in carding or stripping proximity to each other. The terms carding contact or stripping contact where used herein mean carding proximity or stripping proximity as it is not always necessary that the teeth should actually while the term engages covers both carding and stripping proximity. The result of this construction is that the stock S is delivered by feeding-in rolls K and L to licker-in E by which it is carried up and over and picked off by carrier roll A by which it is carried along to the breast D. Whatever flyings or other parts of the stock escape the teeth of carrier roll A continue along and are stripped from the lickerin by the fast running teeth of tumbler F. The stock is carried along by breast D and some is carded between it and first worker C while part of theweb 30 continues along and, is cleared from the breast by the tumbler F. This partcontinues along and is cleared from the tumbler by the teeth of the main cylinder at the point 31 as shown. The other part of the web 32 which is forced into the teeth of the worker is carried along thereby and carded between the first worker and the main cylinder, part continuing along erably progressively on the main cylinder and part 33 being car ried up and back to the transfer roll B by which it is stripped and returned to the breast- D by which the operation is repeated.

It will be noted that the teeth of transfer roll B keep the teeth of first worker C clear between their point of contact therewith and the point of carding contact with breast D. Thereby the carding at the latter point is greatly improved. It will also be noted that the teeth of the licker-in are kept clear by those on tumbler F so that there are no flyings to interfere with the operation of the licker-in. Its teeth being clear, it takes the relatively straight stock of the second breaker and finisher better than if they were not so cleared. This is not as important on the first breaker where the stock at the point between the feeding-in rolls is substantially not carded.

My device consists essentially of the breast cylinder 1), preferably of such size as to be placed between the tumbler and first worker of an ordinary carding machine, and accompanied with the carrier roll which carries the stock from the feeding-in roll to the breast cylinder before it reaches the main cylinder and also with the transfer roll which allows of the reworking of the stock between the breast cylinder and the first worker.

Vith this device, on the same sized card I get an extra carding point, and also secure a reworking of the stock which is of as much or more value than other carding points.

The feeding-in rolls, licker-in, tumbler, main cylinder and first worker are substantially unchanged from the usual arrangement either in size, position, pitch of teeth, direction of rotation, or speed. The first worker may run in either direction as will be hereafter described.

' The breast cylinder is new and the carrier roll which carries the stock from the lickerin to the breast cylinder before it reaches the tumbler is also new. The transfer roll 13 serves partly the purpose of a stripper for the first worker and assists in keeping the points thereof clear in which ever direction the worker travels. Instead of stripping stock from the first worker and replacing it on the main cylinder, it replaces the stock or transfers it to the breast cylinder.

The speeds of the various rolls are preffast increasing from the licker-in to the carrier roll, to the breast, to the tumbler and to the main cylinder. These speeds largely determine the course of the stock. The first worker is relatively very slow and the transfer roll runs faster than the first worker but slower than the breast as described.

Any suitable means to produce the desired speeds may be used and it is unneceslOl sary to explain to one skilled in the art that all the rolls and cylinders described are covered with suitable card clothing and that as the stock proceeds, it is worked by the rolls 10, ll, 20 and 21 and finally taken from the main cylinder H by the action of fancy 12, dofi'ers 13 and delivered to the apron condensers 17 or other receiving devices.

As shown in Fig. 2, first worker C may be revolved in the opposite direction. In such case, the stock 8 is carded, as when the Worker revolves the other way, between breast B and Worker (1, some of it being forced into the teeth of U and being carried along thereby as web 51 which is stripped by the transfer roll B leaving the teeth on first Worker C clear where they come in carding contact with those on the main cylinder. Into these clear teeth, a certain amount of stock is forced by the teeth of the main cylinder and forms a, web which is carded between the first worker and the breast .cylinder part being merged into the web 51 and another part being carded along with the original web S and being carried along at 52 to be stripped from the breast cylinder by the tumbler as in the first described device.

In which ever direction the first worker runs, its teeth will be cleared by transfer roll B at a point before they reach one or the other of its points of carding contact and in either case, the stock is reworked by the breast cylinder.
